Sled Review
The 2013 Yamaha FX Nytro:
An In-Depth Review by Our Snow Goer Canada Staff
On the snow out for a leisurely trail ride.
This past winter Snow Goer Canada
designated our 2013 base FX Nytro as
our “test sled” for the season. We
chose the Nytro for two key reasons;
one, Yamaha had made some seemingly minor changes that significantly
improved handling and ride quality,
and two, to be perfectly honest the
Nytro had always been one of our
least favourite sleds to ride. The main
reasons for this were the twitchy front
end and what we felt were poor suspension calibrations. In short, we
loved the motor but didn’t always
enjoy riding the sled. We wanted to
like it, we tried to like it, but couldn’t.
When our FX Nytro arrived, with
one of the great new wraps, we did a
little research on Totallyamaha.com
to see what Nytro owners were doing
to modify their sleds into more trail
friendly sleds. We added a larger
capacity, aftermarket fuel tank from
Trail Tank and a set of aggressive
carbide runners from Qualipieces for
the Tuner skis. To top it all off, we
also added a set of Elka Stage 5 front
shocks, from Accelerated Technologies, to calm down the front end.
In total we logged a little over
2000 km on the Nytro, approximately 1000km of which with all the
mods, and came away Nytro converts.
We loved it. Even though the writing
is on the wall that the Nytro won’t be
around much longer with the introduction of the new SR Viper, we feel
the 2013 and 2014 Nytro is a great
deal in both price and performance.
In our opinion, the 2013 FX Nytro
(base model) is the best riding and
handling Nytro that Yamaha has
produced.
Fuel Economy
We didn’t keep track of the fuel
mileage on the Nytro this year as this
motor has proven itself over the last
48 Snow Goer Canada September 2013 - 2014 Buyer’s Guide
5 seasons to offer great fuel economy
while delivery excellent power. What
we can comment on is the increase in
fuel range that the Trail Tank delivered with its capacity of 37L over the
stock 28L tank. Fuel range was the
similar to other fuel efficient sleds on
the snow, such as Ski-doo’s 600 SDI
with a 40L fuel tank. An upgrade to a
Trail Tank is highly recommended.
Motor
What can we say that hasn’t been said
before? The acceleration is amazing
and very addicting and the mid-range
hit is instant. Compared to 800
2-strokes on the market, this motor
feels stronger in the mid-range, which
is where most of your riding takes
place. The Genesis 130FI may be
closer in power to 700 class 2-strokes
on paper but the high revs and
torque of the triple cylinder 4-stroke
allow it to compete with higher

Snow Goer-Sept-2013_Layout 1 2013-10-03 10:15 AM Page 49
powered 2-strokes. This is one of our
favourite motors in the industry.
Efficiency and performance don’t
usually come hand in hand but this
motor delivers both very well.
Suspension
For 2013 Yamaha softened the front
and rear suspension calibrations on
the base Nytro to make it more trail
compliant. The front piggyback
shocks were replaced with a pair of
“cheaper”, but lighter, non-piggyback
shocks that actually work pretty well
for normal to aggressive trail riding.
In general, we noticed a significant
improvement in the ride quality from
both the front and rear suspensions
over typical trail bumps at normal
trail speeds. This might not seem like
a big deal but the reality is that it
transformed this mogul-masher-only
sled into a more versatile trail sled
that suited a wider variety of riders.
We could actually trail ride the sled
all day and not get beat up by the
suspension. The base model’s suspension calibrations are very well suited
for both normal and aggressive trail
riding which in all honesty is how
most Nytro owners/buyers ride
their sleds.
It’s no secret that the one major
flaw on the Nytro has always been
the front suspension. They have
always been twitchy and unstable
compared to the competition. The
shock and ski changes to the 2013
model really improve the front
suspension’s performance through
the bumps and corners however it
still wasn’t on par with the competition but, we were convinced we could
improve the performance of the front
end. We spoke with Accelerated Technologies, an Elka shock dealer and
suspension shop in Ontario, about
unlocking the hidden potential from
the Nytro’s front suspension and they
highly recommended trying a set of
Elka Stage 5 front shocks with dual
rate springs. Accel. Tech. worked with
us to determine what low speed compression, high speed compression,

and rebound settings to use. To say
the Elka front shocks drastically improved the ride is an understatement,
the results were very impressive.
Overall the front end soaked up the
big hits and whoops significantly
better than the stock shocks while
actually improving the ride quality
over the small bumps, thanks to the
dual rate springs. It was a huge improvement in every way. The Nytro
became stable and predictable
through 6-12 inch bumps on both
straight stretches and through
corners. We went from having very
little confidence in the front end to
having full confidence that the line
we wanted was the line the sled
would take.
It didn’t take long to realize the
Elka equipped front suspension was
outperforming the rear. If we had had
more time, and less warm weather,
we would have gone a step further
and installed a set of Stage 5 rear
shocks to complete the package however, the front Elka shocks alone are a
highly recommended upgrade.
front end. The Tuners eliminated
darting, allowed for easy steering
effort, and provided great bite in the
corners. The combination of the
Tuners and Ripsaw II track work well
Handling
The single biggest improvement to
the handling came from the dual keel
Tuner skis. They significantly calmed
down the twitchy and unpredictable
Nytro with the Trail Tank installed, hard to
tell the difference from stock.

together to reduce inside ski lift
through corners by allowing the track
to break loose easier. We added a
combination of Qualipieces carbide
runners to our Tuners that provided
light steering but lots of bite in the
corners without being too aggressive.
We ran a 4” carbide on round host
bar on the outside keel with a 6”
carbide on square bar on the inside.
There was still inside ski lift but it was
manageable and much less than past
models without these changes.
When we added the Elka Stage
5 front shocks we experienced a night
and day difference in the handling of
the Nytro. It was at this point that the
sled went from a great handling
Nytro to a good handling sled in
general, even when compared directly
to the competition. There were a few
key factors that contributed to improved handling from the shock
upgrade. Number one was the Stage
5 shocks as they were tuned properly
to how we were going to ride the
sled, number two was the dual rate
front springs, and number three was
adjusting the rear suspension to ensure we were getting the best possible
handling from the sled.
The sled was set up to allow the
front end to sag quite a bit more than
it did stock by keeping a fairly light
preload on the front springs and
tightening the limiter strap on the
front arm of the rear suspension. The
front end of the sled was dropped
over an inch lower than stock which
allowed the A-arms to be more parallel and the skis stance to be at its
widest point. The low speed compression clickers were set so that the sled
resisted body roll through a corner
while the high speed compression
clickers were adjusted so that the sled
was still able to soak up the bumps
through that same corner.
With the Elka shocks installed the
Nytro was a blast to ride. It cornered
as well as other sleds on the market
and definitely the best cornering
Yamaha sled we’d ridden in quite
some time. It felt light and nimble
and was very stable and predictable,
completely opposite to our past
experiences on Nytros.
Comfort
The seating position of the Nytro is
great for aggressive trail riding and
works well for normal trail cruising
as well. The ergonomics are not typical of the other rider forward sleds
on the market but that’s okay with
us, we liked the Nytro’s handlebar
position and found it works well
when standing or when seated and
leaning in the corners.
The addition of the Elka front
shocks improved the comfort of the
Nytro for trail riding however in stock
form this the 2013 base Nytro is the
most comfortable to date.
Wind Protection
The low windshield actually does add
a little wind protection and the hand
guards work well to deflect the cold
wind around your hands however it’s
still a cold sled to ride. It’s intended
to be ridden hard through bumps
and aggressively through the trails,
making the rider sweat, so keep that
in mind. Accessory tall windshields
and deflectors are available.
Accessories & Modifications
Elka Stage 5 Front Shocks with Dual
Rate Springs
The Elka front shocks were a huge
improvement and totally transformed
the sled’s handling and ride characteristics. Accelerated Technologies, of
Buckhorn, Ontario, provided the
shocks with valving, spring rates, and
compression settings selected for the
way we were going to ride the sled.
Every customer gets this treatment.
Accelerated Technologies also went
over the sled and set up the sled for
better handling and also lubed all the
pivot points in the front and rear suspensions to reduce resistance. Every
sled, new or used, can benefit from
this service.

Trail Tank Extra Capacity Fuel Tank
Knowing the small capacity of the
stock fuel tank limited the Nytro’s
range, we opted to add a larger capacity aftermarket tank by TrailTank
High Capacity Sled Tanks. This is
likely the most popular and practical
upgrade you can make to a Nytro.
The capacity of the Trail Tank was
37L, a 9L increase over stock. This
increased the Nytro’s range to the
same as the other efficient sleds on
the market.
The quality was great and install
went smooth thanks to the great
instructions. The hardware that
comes with the tank for fastening the
side panels has been improved over
previous years. Everything you need,
including gaskets, o-rings, and fasteners comes with the tank. They are also
available in black or clear, we prefer
the clear that way you know exactly
how much fuel is in the tank as the
fuel gauge will not be 100% accurate
with the increased capacity. SGC
highly recommends this upgrade.

Qualipieces Carbide Runners
In the fall SGC spoke with Qualipieces
about a combo of carbide runners for
the Nytro with the Tuner skis. Qualipieces was happy to provide 3 sets of
runners that they had tested in various
combinations the previous winter. We
had a super aggressive combo and a
semi-aggressive combo. We stuck with
the semi-aggressive set up as this

worked great to provide good bite in
the corners but didn’t overpower the
Ripsaw II track or add to any inside ski
lift. We used a round bar with 4” of
carbide on the outside keel and
square bar with 6” carbide on the
inside.
Durability was excellent. We
logged closer to 2000 km on the
carbides and showed little wear,
plenty of life left for another season
The amazing Genesis 130FI engine Just like most reviews of a Yamaha
sled we’ve done, we loved the motor.
The mid-range punch of the 135+ hp,
inline triple 4-stroke is nothing short
of awesome. A very fun, efficient, and
reliable motor that is just as happy
being ridden hard as it is cruising.
Tuner skis – Why couldn’t Yamaha
have had these on the 2008 Nytro?
They work very well with the Nytro
and we strongly recommend upgrading your Nytro with a set of Tuners.
Improved ride quality on the trails
– The softer shock and spring calibrations on the base Nytro made a big
difference in the ride quality for
typical trail riding.

Dislikes
Lack of storage – Even though this is
intended as an aggressive trail sled
the reality is most sleds go out for
long days of riding. An area to store
extra gloves, hat, maps, or whatever is
needed.
We don’t think it should be necessary to modify a sled so much to get
it on par with other sleds in the handling and ride quality department.
But, adding aftermarket parts is half
the fun for some riders.
The front suspension geometry –
It’s too bad the Nytro didn’t come
with the racing front end that
Yamaha has been using on the cross
country circuit. This sled had the potential to have more of an impact on
the market but fell short due to the
twitchy front end. •
